Hello all,
I have a program that use parallel toolbox. That works perfectly in Matlab but when I compile it and execute it in cmd.exe, I get this error: Matlab cannot determine whether 'gmdistribution' refers to a function or variable. See Parallel for Loops in Matlab, 'Unambiguous Variable Names'. Matlab:mir_error_parfor_ambiguous_name.
The program crashes in this row:
gm{k} = gmdistribution.fit(X,ngseq(k),...
'Regularize',Regularize,...
'Replicates',Replicates,...
'Start',Start,...
'CovType',CovType,...
'SharedCov',SharedCov,...
'Options',gmoptions);
I'm using matlab (2014a) and mcr 8.3 (2014a)| Thank you

i have the same problem. even if i change the parfor to a for, the compiled code errors out on gmdistribution saying it is an undefined variable or class. this is with 2014a on 64-bit linux. works fine on the command line though.

Hi,
I'm not sure yet about the parfor part of the question. You are right, the compiler should pick up the code automatically. As a workaround you can help him here by adding the folder matlabroot\toolbox\stats\stats\@gmdistribution to the "Files required for your application to run". It should then add all files of that folder, and then (at least without parallel computing) it works. Since in this case parfor "knows" what gmdistribution.fit is, my guess is, that the parfor problem will go away as well.

Hi,
I just made another test: replacing gmdistribution.fit by fitgmdist (as the help for gmdistribution.fit suggests, because gmdistribution.fit will be removed) solves the problem as well.
It looks as if the compiler is one step ahead of MATLAB ;-).
